I have just started to get this error. I am using a Windows 7 machine & LR 4.3.
Here is my workflow:
Save images - JPGs only - on home server
Import images into LR using "Add" option
Go through the images in library for my initial pass
Mark images as rejected or certain # of stars
Immediately I get the overwrite error on the images I mark
I select the "overwrite settings" option
The error icon returns.
These images have not been opened in any other program since initial import or even before.
Any recommendations to resolve this error?
